Examining the metadata (outside Serviio) for these tracks it is correct.This appears to be an occasional error in the indexing process.

By editing the metadata say by adding a space in the comment field results in the track being re-indexed and classified in its correct genres category (without any change having been made to the Genres).

Usually there may be just one or two tracks from an album (bearing in mind an album usually has the same genres set for all tracks) in the "Unknown" category.I can see no pattern and the tracks come from differing Genres.

IMPORTANTLY I have just discovered that these tracks are not in the Artist/Album lists !!!!!! i.e. THEY ARE MISSING FROM THE ALBUMS in the Control App.

(this is not a new issue as I have used my workaround that clears them up in the past. I was not aware they were missing from the albums).Force Refresh does not appear to resolve this issue. Also if you do not have Genres enabled as a display option you may never know the tracks are missing.I think this is an urgent bug.

Force Refresh (as I indicated) does not clear these items.I have tried it again twice.

Having updated some tracks with amended artwork I now have some more "Unknown" genres items.Again they do not appear in the Artist, album, or album artist indexes.Example Nilsson tracks 1, 5, 11,12 and 15 are in unknown genres AND are all missing from indexes (see attachments).

I enclose log files that trapped items going into the genres/unknown category.

I amalgamated three folders of "The Very Best of Legends" (Disc 1, Disc 2, Disc 3) into a single album folder.This involved changes to the metadata for album name, disc no , track names and track numbers.

A number of the files (13 of 65) went into genres/unknown.The 13 do not appear in the Album/Artist indexes.

Is it the same version that indexed with Unknown genre? I wonder if it can be something to do with the metadata tool and how it stores data. Maybe it makes the updates in phases, Serviio detect the initial step (with missing data), and then ignores the other phases (when it fill the metadata back in) ... totally guessing though.

PetrServiio developer / site adminDo not send me PM for support as the solution can't be shared with others.

It is the same file version that identified as unknown.It did clear when I reran later as did the other 12 files.The metadata tool is dBpoweramp Edit ID Tag (in this case Multiple Files version).I was running it over the network to the library files so your theory about timing and phases may be correct.

However I currently have three files in unknown that were edited and then uploaded as files so timing and phases may not be true in this case.I can send these files if you wish.Also "Force Refresh" appears not to see these "missing" files so they stay missing.
